“…The growth of A. ammonioxydans with raise in Phenanthrene concentration (Preethi et al,2023) was investigated by inoculating the organism into LB medium supplemented with varying Phenanthrene concentrations (2.5 to 12.5 mg/ml) as a sole carbon source. The optical density of the LB medium was measured immediately and after 24 hours of incubation at 100 RPM and 27 ± 2℃.…”

The compound, Phenanthrene, a three-ring polyaromatic hydrocarbon (PAH) commonly occurs in the environment and it is derived from grilled meals, tobacco, crude oil, coal tar and automobile exhaust among other sources. Phenanthrene has been identified as a potentially hazardous PAH. Bioremediation is the most popular way of elimination technique since it is a sustainable solution that results in full mineralization of Phenanthrene. In this study, we aim to perform the biodegradation of phenanthrene by using the strain, Alcaligenes ammonioxydans (VITRPS2) which is isolated from petroleum-contaminated soil. At 5 mg/ml, the degradation rate constant was found to be 0.0181/day with half-life values of 2.7 as per first-order kinetics and 4.49 as per second-order kinetics. We employed one factor at a time (OFAT) approach to optimize the biodegradation conditions of the strain within the framework of Luria‐Bertani (LB) media. The isolate exhibited the ability to achieve maximum growth of 5mg/ml of phenanthrene as the exclusive carbon source under optimal conditions. These conditions included a pH level of 8.0, an inoculum concentration of 8%, along with a temperature of 37°C throughout 7 days of incubation period. The strain exhibited a degradation efficiency of up to 72% for phenanthrene, given optimal environmental conditions. The gas chromatography-mass spectrometry (GC-MS) analysis of the breakdown products unveiled the existence of the principal metabolites of the pathway, such as salicylic acid, catechol & various phthalic acid derivatives. The strain demonstrates that there are considerable potential applications in the remediation of an environment polluted by polycyclic aromatic hydrocarbon (PAH) metabolites.

This article emphasizes the various contributions of actinobacteria to the well-being of human life on our planet. Agrarian virtues begin with the substitution of chemical fertilizers with bio-fertilizing microorganisms which have a versatile potential for the benefit of soil and plants by playing complementary and interconnected roles. Thus, these microorganisms improve soil health through bioremediation phenomena and the elimination of several non-beneficial microorganisms. In agriculture, these microorganisms can be added to compost as inoculants to speed up the composting process and provide an additional source of beneficial microorganisms for the compost-treated soil. Streptomyces and other actinobacteria can also be used as biotechnological sources of herbicides and insecticides. In the medical and therapeutic sectors, this paper emphasizes the potential of actinobacteria, in particular Streptomyces species, in the production of antibiotics, antioxidant, and anticancer agents, opening up avenues for the creation of molecules with high benefits. In biotechnology, these totipotent microorganisms produce enzymes widely used in several industries, generating considerable revenue. Sporadic data accumulated on these types of microorganisms opens up many new avenues for exploiting these natural biocatalytic resources. Papers published in the last decade have exploded the amount of information that can be put to practical use. To maximize the value of these microorganisms, it would be advisable to create common threads between the themes that bring together the areas of expertise where these microorganisms could potentially be exploited. This bibliographical synthesis is a contribution to the development of a targeted database.
